It's because people like to sound smart, and using the long words that other people has the benefit of making them look smart and having a similar opinion to other people. Hell, go into any heavy debate nowadays and you could play a drinking game with how many times people use words such as straw-man, false equivalence, ad hominem and so on completely incorrectly.
As for the point about when Bioshock does actually have ludonarrative dissonance, that pretty much comes down to people trying to make excuses for why they don't like things because they cannot find a proper reason to express it without simply saying "It doesn't fit my personal tastes". You see this all of the time when people will randomly decide when being "unrealistic" is a problem, and when it is perfectly okay.
To use Tomb Raider as an example some people wanted to act as though Lara's outfit was a problem because she never wore more appropriate clothing for a person in frequently harsh climates. But being shot several times and magically healing, being able to climb rock walls with the dexterity of a person who dedicates their life to it and being an expert marksmen within several minutes of first picking up a gun are perfectly acceptable.
It's also quite frequently a case of people picking up the word but not actually comprehending the specific meaning of it. The mainstream media keeps referring to "internet trolls" in their articles when the people they are describing are not trolls at all. They seem to have mistaken the fact that being nasty to somebody online is not the meaning of trolling, it just happens to often coincide with it, yet most articles referring to trolling simply use it as another term of bullying, harassing or threatening.
